Cyclophorus serratizona Hanley & Theobald, 1876

Cyclophorus serratizona Hanley & Theobald, 1876: 57, pl. 144, fig. 7. Kobelt 1908: 654. Gude 1921: 77.

Type locality.

Upper Salwen [Myanmar].

Type material.

Possible syntypes NHMUK 88.12.4.1955 (3 shells, Fig. 19B; D =37.1 mm, H=30.0 mm, W=5; D=39.9 mm, H=30.8 mm, W=5; D=40.7 mm, H=32.9 mm, W=5).

Remarks.

This taxon was described based on specimens from the Theobald collection. Coan and Kabat (2012: 326) stated that the types could not be located in either the NHM or the Leeds Museum. We located 3 specimens in the NHM general collection with a label stating that they were purchased from Theobald, "type figd in C. I.", but giving Moulmein (currently Mawlamyine), farm (=from?) caves, as the locality, which is at the mouth of the Salween. It seems likely that there is a mix up in the documentation of the locality but we cannot determine if the error is in the locality given in the original description, an error in the labelling with the specimens or if this lot is simply not type material. We therefore treat the material as possible syntypes.

The locality given by Hanley and Theobald was Upper Salwen (Salween or currently Thanlwin). However, the material identified as the syntype series carries labels giving Moulmein (currently Mawlamyine), farm (=from?) caves, as the locality, which is at the mouth of the Salween. As the Salween is close to 3,000 km in length and the river originates from the Tibetan Plateau, it is clear that 'Upper Salwen’ is inaccurate. It is conceivable that the intended record was Upper Myanmar but on current evidence we conclude that the Mawlamyine is the type locality.
